CHARLOTTE, N.C. (AP) — More than 80 members of the United Blood Nation gang have been indicted as part of a five-state crackdown on gang activity, federal authorities announced Thursday.

A news release from the U.S. Department of Justice said more than 600 federal, state and local law enforcement officers carried out the arrest warrants in Charlotte and other locations across North Carolina. Arrests were also made in South Carolina, Virginia, Florida and New York.

“Today’s law enforcement action delivered a serious blow to the leadership structure throughout the ranks of this criminal organization,” U.S. Attorney Jill Rose said. “And this is only the beginning.”

A federal grand jury returned the indictments on Monday. Of the 83 people named in the indictments, officials said 27 are already behind bars and 10 are still at large.

Prosecutors say gang members engaged in racketeering activity, including murder, attempted murder, narcotics distribution and firearms possession. The indictment also says gang members engaged in bank fraud and wire fraud.

Allegations contained in the indictment said that, beginning by at least 2009 and continuing until the present, the defendants were leaders and members of the UBN’s Nine Trey Gangsters. Members engaged in racketeering activity, including murder, attempted murder, assault with a deadly weapon, robbery, narcotics distribution and firearms possession.

The indictment also says that some defendants engaged in bank fraud and wire fraud to generate proceeds to pay gang dues, maintain membership with the gang, discipline other gang members and to be promoted within gang leadership.
